The signal receiving plate of a metal detector is an important part of the metal detector and its role is to receive and process the signals generated by the metal detector probe.
The probe of a metal detector is usually a coil of wire, and when a metal object passes through the probe, it changes the electromagnetic field of the probe, resulting in a weak electrical signal. This signal is amplified by an amplifier inside the probe and sent to the signal receiving board.
There is usually a filter on the receiver board that filters out interfering signals other than metallic signals. The receiver board then processes and analyzes the metal signal to determine if a metal object passes through the probe.
If a metal object passes through the probe, the receiver board sends an alarm signal to notify the operator that a metal object has been detected. In addition, the signal receiving board can also transmit information about metal objects to a computer or other device for further analysis and processing.
In summary, the signal receiving board is a key component of the metal detector, its role is to receive and process the signal generated by the probe, so as to achieve the detection and alarm of metal objects.
